Ultipotence should be immune to it, they are not Omnipresent by default so they would have to consciously make the decision to become Omnipresent, and I know how much you just LOVE taking about that last point (and the contriversy around omnilock) but before you ask read the trivia part in omnipotence.
@Nekron2:Actually, your last point is entirely dumb you should have seen the trivia of the omnipotence page before asking.
@Holder rhanks for ending this matter quickly otherwise it would have evolved into an another age long debate.
i know this is late but
yes ultipotence is omnipotence without omniscience so it can do anything like omnipotence do and no omnipotence and ultipotence cannot exist in the same verse (fiction).
